Fejervarya Triora
''Fejervarya triora'' is a species of frogs belonging to the family Dicroglossidae. Its type locality is in Phu Chong-Na Yoi National Park, Ubon Ratchathani Province in the far east of Thailand. It is also known from Mukdahan National Park in Mukdahan Province, and also Pha Taem National Park, Ubon Ratchathani Province. So far, it is only known from eastern Thailand, although it is not unlikely that it occurs in adjacent Laos too. It has been found in a range of forested habitats. Description ''Fejervarya triora'' is a robustly built frog, females having a body length of up to in snout–vent length (SVL). The only known male measures SVL. The warty upper parts are olive brown with green blotches, the underparts are greyish white. There is an orange spot on the lower half of the tympanum and yellow and black patterning on the legs. The iris is bronze-coloured. When compared to other ''Fejervarya'' species found in the region, ''F. triora'' can be distinguished from '' F. r ...

Tympanum (zoology)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Endemic Fauna Of Thailand
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fejervarya
''Fejervarya'' is a genera of frogs in the family Dicroglossidae found in Asia. First proposed in 1915 by István József Bolkay, a Hungarian naturalist, the genus did not see widespread adoption at first. As late as the 1990s it was generally included in ''Rana'', but more recent studies have confirmed its distinctness. These frogs are remarkable for being extremely euryhaline by amphibian standards. Species such as the crab-eating frog (''F. cancrivora'') can thrive in brackish water, and its tadpoles can even survive in pure seawater. Systematics and taxonomy ''Fejervarya'' was first introduced as subgenus of ''Rana'' and later placed as subgenus as ''Limnonectes''. It was treated as an independent genus first in 1998. However, ''Fejervarya'' sensu lato was found to be paraphyletic with respect to '' Sphaerotheca''. This issue was eventually resolved in 2011 by splitting some species to the genus '' Zakerana'' (renamed in 2021 as '' Minervarya''). ''Fejervarya'', as now ...

Tadpole
A tadpole is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fossils would not exist. However, traces of biofilms have been preserved and fossil tadpoles have ...

Fejervarya Limnocharis
''Fejervarya limnocharis'' is a species of frog found in South East Asia and parts of Indochina. It is known under many common names, including Boie's wart frog, rice field frog, and Asian grass frog. Molecular studies of the species complex (after Boulenger) suggest that there may be multiple species involved. Description Snout pointed, projecting beyond mouth. Canthus obtuse, loreal oblique, more or less concave. Internarial space is longer than interorbital width, which is much less than width of the upper eyelid. Tympanum distinct, half to twothirds the diameter of eye. Fingers obtusely pointed, first longer than second, subarticular tubercles very prominent. Tibiotarsal articulation reaches tympanum or naris. Toes obtuse or with slightly swollen tips, half webbed, subarticular tubercles small and prominent. Body with small tubercles, sometimes small longitudinal folds are present, ventrum smooth except belly and thighs which are granular posteriorly. Male with loose gular reg ...

Fejervarya Raja
The crab-eating frog (''Fejervarya cancrivora'') is a frog native to south-eastern Asia including Taiwan, China, the Philippines and more rarely as far west as Orissa in India. It has also been introduced to Guam, and was most likely introduced from Taiwan. It inhabits mangrove swamps and marshes and is one of only 144 known modern amphibians which can tolerate brief excursions into seawater. This frog can tolerate marine environments (immersion in sea water for brief periods or brackish water for extended periods) by increasing urea production and retention, and by remaining slightly hyperosmotic within urea and sodium flux. Adults can survive in salt water with salinity as high as 2.8%, and tadpoles can survive salinities as high as 3.9%. Diet The food sources of the crab-eating frog are mainly determined by the locally available prey. Near fresh water, its diet consists largely of insects. But in an environment with brackish water, small crustaceans, including crab Crabs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pha Taem National Park
Pha Taem National Park (Thai:อุทยานแห่งชาติผาแต้ม) is a List of national parks of Thailand, national park on the Mekong River in Ubon Ratchathani Province, northeast Thailand. Phou Xieng Thong National Protected Area in Laos is on the opposite side of the river. It is notable for its Dipterocarp forest cover and for extensive rock art on cliffs above the Mekong. The art is estimated to be 3,000 years old. The park also has several examples of mushroom rocks as well as the largest flower field in Thailand. Pha Taem National Park is a popular destination for the first sunshine of the New Year to fall on Thailand. Pha Taem National Park was declared a national park on 31 December 1991, with an area of 212,500 rai ~ . History In the past, only a few local peasants from the surrounding region dared to access the Pha Taem area. Because it is believed that Pha Taem is a prohibited location, and the mountain is protected by the holy. Pha Taem i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
